a “‘Fornication’ in the broad sense, and as used at Matthew 5:32 and 19:9, evidently refers to a broad range of unlawful or illicit sex relations outside marriage. Porneia [the Greek word used in those texts] involves the grossly immoral use of the genital organ(s) of at least one human (whether in a natural or a perverted way); also, there must have been another party to the immorality—a human of either sex, or a beast.” (The Watchtower, March 15, 1983, page 30) Adultery: “Voluntary sexual intercourse between a married person and a partner other than the lawful husband or wife.”—The American Heritage Dictionary of the English Language.
